2. Power the Receiver: Connect the power adapter to the DC Power Plug on the receiver and plug it into a power outlet.
3. Connect to Audio System:
   • For a mixed output, use the 1/4" audio cable to connect the receiver's MIX OUTPUT to an input on your audio mixer or amplifier.
   • For individual microphone control, use XLR cables (not included) to connect the receiver's AF OUTPUT (XLR) for Channel A and Channel B to separate XLR inputs on your audio mixer.
4. Install Microphone Batteries: Unscrew the bottom part of each handheld microphone to access the battery compartment. Insert 2 AA alkaline batteries into each microphone, ensuring correct polarity.
5. Power On Receiver: Press the Power Switch on the receiver's front panel. The LCD display should light up.
6. Power On Microphones: Slide the ON/OFF switch on each handheld microphone to the "ON" position. The microphone's LCD display should light up, and the RF indicator on the receiver for that channel should illuminate.
7. Adjust Volume: Start with the Volume A and Volume B knobs on the receiver at a low setting. Gradually increase the volume on your audio mixer/amplifier and then fine-tune the individual microphone volumes on the receiver.

5. Operating Instructions

5.1 Basic Operation

• Power On/Off: Use the power switches on the receiver and microphones as described in the setup section.
• Volume Control: Adjust the individual volume knobs (Volume A, Volume B) on the receiver to balance the microphone levels. Further adjustments can be made on your connected audio mixer or amplifier.
• Speaking/Singing: Hold the microphone approximately 2-6 inches from your mouth for optimal sound pickup.

5.2 Range and Performance

The innopow WM200 system provides a working range of 150-200 feet (approximately 45-60 meters) in wide-open areas. Obstacles such as walls, metal structures, and other electronic devices can reduce this range. Ensure a clear line of sight between the microphones and the receiver's antennas for best performance.

Figure 5.1: Wireless Range Illustration. This diagram visually represents the effective working range of the wireless microphone system, showing signal strength at distances up to 200 feet.

5.3 Fixed Frequency Operation

This system operates on fixed UHF frequencies (CH.01 & CH.02). This means the frequencies cannot be changed. Due to this design, it is important to note the following:

• Single System Use: Only one innopow WM200 system (CH.01&02) can be used at the same location and time to avoid interference.
• No Mute Feature: The microphones do not have a dedicated mute button. To temporarily stop audio transmission, you must turn the microphone OFF using its power switch.

6. Maintenance

6.1 Battery Replacement

Each handheld microphone requires two AA alkaline batteries. The system provides 14-17 hours of continuous use with fresh batteries. When the microphone's LCD display shows a low battery indicator, replace the batteries promptly to ensure uninterrupted performance.

• Unscrew the bottom cap of the microphone.
• Remove the old batteries and dispose of them responsibly.
• Insert two new AA alkaline batteries, observing the correct polarity (+/-).
• Screw the bottom cap back on securely.

6.2 Cleaning

To maintain the appearance and functionality of your system:

• Wipe the receiver and microphones with a soft, dry cloth.
• Do not use abrasive cleaners, solvents, or harsh chemicals.
